General informations

The Linux kernel configuration item CONFIG_MTD_ONENAND_VERIFY_WRITE has multiple definitions:

Verify OneNAND page writes found in drivers/mtd/nand/onenand/Kconfig

The configuration item CONFIG_MTD_ONENAND_VERIFY_WRITE:

• prompt: Verify OneNAND page writes
• type: bool
• depends on: (none)
• defined in drivers/mtd/nand/onenand/Kconfig
• found in Linux kernels: 4.17–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

This adds an extra check when data is written to the flash. The OneNAND flash device internally checks only bits transitioning from 1 to 0. There is a rare possibility that even though the device thinks the write was successful, a bit could have been flipped accidentally due to device wear or something else.
